Overview
Calcium targets are specialized materials used in physical vapor deposition (PVD) techniques such as sputtering and electron beam evaporation. These targets consist of high-purity calcium metal, typically shaped into discs or rectangles to fit deposition systems. In industrial and research settings, calcium targets enable the production of thin films with unique properties, such as high reactivity or specific optical characteristics. Their applications span semiconductor device fabrication, protective coatings, and advanced material research.
Physical and Chemical Properties
Calcium is a lightweight alkaline earth metal with a silvery-white appearance. As a target material, it is prized for its high purity (often ≥99.9%) and uniform microstructure, which ensures consistent deposition rates. Key challenges include its reactivity with moisture and oxygen, requiring careful handling and storage. Manufacturers often optimize grain size and density to minimize outgassing and improve film quality during high-vacuum processes.
Main Applications
The primary use of calcium targets is in thin film deposition for electronic and optical components. In semiconductor manufacturing, they contribute to gate dielectric layers or as dopant sources. Other applications include anti-reflective coatings for optics, barrier layers in flexible electronics, and research into superconducting materials. Recent advancements also explore calcium-based films for battery technologies and catalytic surfaces.
Safety and Storage
Due to calcium's high reactivity, targets must be stored in sealed containers under inert gas (argon preferred) with desiccants. Exposure to humid air can form hazardous hydroxides and oxides. Processing requires glove boxes or controlled environments. Waste disposal must follow local regulations for reactive metals, often involving slow neutralization in alcohol before landfill.
B2B Procurement Guide
When sourcing calcium targets, prioritize suppliers with ISO-certified cleanroom facilities and traceable material certifications. Key specifications include: 1. Purity level (standard 99.9% or ultra-high 99.99%) 2. Target dimensions and thickness tolerances 3. Backing plate material (e.g., copper for bonded targets) 4. Surface roughness (typically <5µm) Lead times can range from 2-8 weeks for custom configurations. Consider requesting deposition test reports for critical applications.
